My spouse is on a very expensive treatment. For the first 5 years or so, the insurance company would call us every six months to ask if we had other insurance because they do not like paying for it. I think they’ve finally stopped asking. Next, they started harassing our doctors telling them to switch her Rx over to their (fucked up) internal pharmacy. Luckily the doctor knew they couldn’t be forced to do it and called us about it. We had to call the insurance company and tell them we aren’t changing pharmacies and to stop calling us or our doctors about it. They continued to call for a few months but have apparently relented.
